This provides a major review of the two-level system Kondo model, as applied to metallic glasses, nanoscale devices and some doped semiconductors; and the quadripolar and magnetic two-channel Kondo models developed for rare-earth and actinide ions with crystal splitting metals. These contrast with the simple single-channel model, and allow the study of non-Fermi liquid physics. This book forms a valuable and unique source of information for statistical and condensed matter physicists and graduate students.
* An invaluable and unique source of information on this highly popular area of condensed matter physics
* Based upon a special edition of the Advances in Physics journal
* Magnetic impurities in metals present a major challenge to condensed matter physicists, for which a strong starting point has long been the early insights of Kondo into the resistance medium
